Alright, folks. We’ve got some good news and bad news for all the people who have been pestering their carriers, phone makers, and us about when their phones would be get the Android 2.2 (Froyo) firmware update. AT&T and Samsung announced today an update is possible for Samsung Captivate users right. now. Sadly, that update is applied through the Samsung Kies software that is only available for PC users. Anyone on a Mac needs to find a friend who will let them install the software or is SOL. Download the update for your Windows XP/Vista/7 PC here and follow all of the nifty instructions that Samsung has provided.

As for you HTC Aria users, you’ll have to keep an eye on the AT&T Facebook page. Tomorrow, the site will provide “a link to learn how to download the update.” Remember that everything that comes with Froyo will not be available in the Aria because it doesn’t have the hardware necessary to run some of the features you might see in the Captivate. But you will get a JIT compiler that will speed up app performance and web browsing, so chin-up about that.

Meanwhile, Epic 4G users just can’t catch a break. After finally getting word of an OTA going out and getting the option to manually install, word has come that Sprint and Samsung have halted the update because of problems. Some users reported phones having trouble with calendars or microSD cards, so Sprint is working to fix this before sending out more updates. If you have already downloaded the update and are experiencing issues, you might want to try a hard reset. Backup your crucial data and then follow the steps provided in this Sprint community help thread.
